Answer:
Option 1 and 3 are continuous graph.
Step-by-step explanation:
We have been given the four graphs we need to tell which one among these given graphs is continuous
Option 1 is continuous since, there is no break in the graph and points are joint that is a straight line.
Option 2 is discrete graph it is not continuous because these are points which are not joint.
Option 3 is continuous since, there is no break in the graph and points are joint that is a straight line.
Option 4 Option 2 is discrete graph it is not continuous because these are points which are not joint.
The amount of energy it takes to run a race is most likely to be a function of the; D: Length of the Race
<h3>How to find amount of energy?</h3>
We want to basically find the factor that influences the amount of energy expended by a sprinter.
Now, formula for potential energy is;
P = mgd
where;
m is mass
g is acceleration due to gravity
d is distance covered
Now, the only option that falls into the input that affects energy expended is the distance covered. This is true because the more the distance covered, the higher the energy expended.

#SPJ1
False. This is because no matter what the number is, the properties of multiplication and division stay the same. So, if one odd and even number multiply/divide, then the answer will be negative. But, if two numbers of the same sign (both either negative or positive) are divided/multiplied, they will both be positive. Therefore, the result is not always the same sign as the starting integers

The type of cost that is associated with the state the car was purchased is C. tax, title, and registration.
<h3>Why are these associated with the state of purchase?</h3>
Different states in the United States have different requirements for registering a car after purchase.
There are also different tax rates charged per state, and the title requirements of the car are different by state as well.
In conclusion, option C is correct.

Answer:
a. H0:μ1≥μ2
Ha:μ1<μ2
b. t=-3.076
c. Rejection region=[tcalculated<−1.717]
Reject H0
Step-by-step explanation:
a)
As the score for group 1 is lower than group 2,
Null hypothesis: H0:μ1≥μ2
Alternative hypothesis: H1:μ1<μ2
b) t test statistic for equal variances
t=(xbar1-xbar2)-(μ1-μ2)/sqrt[{1/n1+1/n2}*{((n1-1)s1²+(n2-1)s2²)/n1+n2-2}
t=63.3-70.2/sqrt[{1/11+1/13}*{((11-1)3.7²+(13-1)6.6²)/11+13-2}
t=-6.9/sqrt[{0.091+0.077}{136.9+522.72/22}]
t=-3.076
c. α=0.05, df=22
t(0.05,22)=-1.717
The rejection region is t calculated<t critical value
t<-1.717
We can see that the calculated value of t-statistic falls in rejection region and so we reject the null hypothesis at 5% significance level.
